June 24, 1933, -Serial No. Divided and this application March 16,181. InGreat Britain and Germany October 21, 1933 15 Claims. (01. 199-46) Thisinvention relates to typographical machines, such as those of thegeneral-organization represented in Letters Patent of the United StatesNo. 436,532 .to O. Mergenthaler, wherein circus lating matrices arereleased from a magazine in the order in which their characters are toappear in print and'then assembled in line, thecomposed line-transferredto the face of the mold, the

moldfilledwith molten metal'to form a slug against the matrices whichproduce the type char- 'actersthereon and the matrices thereafter,elevated and "returned through distributing mechanismto'the magazinefrom .Whichthey started. More particularly, it relates to machineswhere'- in=the magazine is pivotally mounted in the machineirameandismovabl'efroma position parallel'wlth the magazine supporting frame;wherein it cooperates with the matrix releasing escapenients'whichremaininth'emachine at all times, to ap'osition clear of the escap'ementatofacili- "tate the'removal *of'th'e magazine and its replacerfrrentbya'magazine containing a-different matrix ont.

H "The presentinvention is directed to certain improvements in machinesof the class-stated, and-intended to simplify the construction andf'acilitate'the locking or thematrices'in the magprior to'the removalthereofflfrom-the'machine. 'To this'end, the magazine containing theil'iiferent fontswith-which the machine-is adapted equipped are providedI each with a' matrix 'toekingbar'whichis automatically shifted toactive-position as the magazine is separated from the escapementmechanism to facilitate its removaL and the locking bar of thesubstitute magmine aiitomatically 1 shifted to inactive 'position assuch magazine isbrought into engagement with the escapement mechanism topermit the operation thereof in the usual manner to releasethermatrices.

'iInwanother 10f its aspects, the invention comprehends arrangementwhereby i the. matrices in=themagazine on the machine may betransie'rred to' a storage magazine andother matrices transferred froma=secondstorage magazinerto the main magazine without removing'the'latter from E the i machine.

This application is a division of my copending application serial No.677,417 filed June '24, 193-3.

' :Reerring to the drawings:

2 is a side elevation similar to Fig. l, with I the parts innormalposition;

Fig.3 is'a side elevation similar to Fig. 1, showing the "parts inaposition just prior to raising the magazine from the frame;

' Figs. 4 and 5 are partial front elevationsofthe parts shown in Figs. 1to 3; I Figs. 6 and? arepartial sectional views on lines 6-'6,and11-+'lof'Figs. 2 and .1, respectively; Fig; 8 is a side elevation of. aportionof the machine, showing the devices .for transferringmatrices'from and to the main magazine without removing the latter from.the machine; Fig: 9 is a partial front View of the parts shown inFig. 8;and I Fig. '10 is 'a section, partially broken away, on line |0l0'ofFig-Q8. p 1'. The matrices are stored'in a channeled mag azine A restingon a base frame A and pivotally mounted inthe machine topermitmovementinto so and out of operative position with the usual assemblerentrance or raceway (not shown blltpO sitioned as usual atthe lower endof the magazine). The magazine in its operativeposition cooperates witha bankpf escapements A fixed to the base frame and operated in the usualway froma keyboard mechanism to release the mat rices one at aatime forstacking in the assembler (not shown) to form a composed line. There'-after'the' line is transferred to the first-elevator or transporterwhich descends to present the com posed line to1the mold,'the moldadvanced into close contact with thematrix line, the mold-filled withmolten metal to form a slug against the matriceswhich produce the typecharacters therei r on, and thematricesthereafter elevated. and returnedthrough a "distributing mechanism .'po'si'- tioned at the upper end-ofthe magazine Al'tO the respective channels of the magazine from whichtheyzstarted. L 40 Inorder that different-fonts-may be used, with themachine, the magazine A, as previously stated, "is pivotally:mounted inthe machine -so that it may be raised from its normal position, parallelto the magazine-supporting,frame A to effect its removal and replacementby a magazine containing a different font. When the mag: azine. A.isin'its'normal position, the matrices, of course, are held thereinbythe escapementpawls which cooperate with the upper projecting ears .ofthe matrices to effect their' release one at a time, but when themagazine A is separated'from the escapements A some means mustbeprovided for locking the'matrices to prevent them from spilling out ofthe magazine.

As more fully described in my Patent No.

sition shown in Figs. 2 and 4, with hook portions a engaging at oppositeends of the customary forward transverse rib a on the undersideof themagazine to hold the latter securely in position.

The magazine supporting frame A is" provided with a central magazinelifting and supporting plate A (Fig. 8) pivoted at its upper end to theits lower end, ders a normally engaged with the rib a and which thusretain the plate A when the latter is in its raised. position.

In the embodiment illustrated, the swinging of the magazine lifting andsupporting plate A is controlled and effected by a cam a or equivalentdevice arranged near the lower end thereof and fast, to the transverserock shaft A journalled in the base frame A Thus, when thehand levers AA5 are pulled forwardly, the magazine is first released from themagazine frame by the disengagement of the hooks a with the rib on themagazine, and the magazine raised by the engagement of the cam a withthe magazine v supporting plate A this action resulting in the separation ofthe magazine from the escapements A When the. magazine isseparated from the escapements, the matrices are prevented from spillingout by a locking bar A extending transversely of the magazine, andprovided with a series'of depending teeth a at its front edge, which areadapted to stand across or in front of the lower mit the release ofzine.

The transverse movements of the locking bar are effected automaticallyby a pair of cams a", a, one mounted on each of the hand levers A A, thecam a on the left having a surface a slopinginwardly toward the side ofthe magazine and which engages the left end of the locking bar surfaceare complementary in nature, the slope of the cam surface a on the rightproviding the necessary clearance for the locking bar as it is actuatedto the right by the locking cam a", and the slope of the surface a ofthe latter cam providing the necessary clearance for said bar when it isactuated to the left under the influence of the unlocking cam all.- i pAs shown in Figs. 6 and 7, the rear faces of the teeth a are bevelled,so that as they are projected across the magazine channels by themovement erative relation with magazine in place on'the of the lockingbar A to the right, they will push the matrices rearwardly a slightdistance, and thus provide clearance between the matrices and theescapements as the magazine is removed from or replaced in the machine,The bevelled surfaces also facilitate the cooperation'of the teeth withthe matrices.

, In order to maintain the bar A in its locking position when themagazine is removed, the latter is provided at the right with a pivotedlocking pawl a arranged to enter a notch a in the upper edge of the .barA when the latter is in its locking position (Figs. 1 and 7). The lowerportion of the pawl a engages on the top of the escapement frame A whenthe magazine is in opthe latter (Fig. 2), thus maintaining the pawl inits inactive positon against the push of a spring pressed pin a bankingon the rear edge thereof. ,Just prior to the disengagement of themagazine from the escapements, the locking bar A is actuatedjto lockingposition, bringing thenotch a in registry witli the pawl a (Fig. 7), sothat as the magazine is raised from the escapements and the pawl freed,the latter is pushed forwardly. into thenotch by the pin a therebyretaining the bar A in lock ing position. When the magazine is againbrought into cooperative relation with the escapee ments, the pawl abanks uponthe top of the escapement frame A and thereby is withdrawnfrom the notch a 'to release the locking bar.., f I

In Figs. 8 to 10, there is shown an arrangement whereby the matrices inthe magazineonfthe machine may be transferred, to a storage maga zineand other matrices transferred froriianother storage magazine to themain magazin'elwithout removing the latter-"from the machine.

The storage magazines A A l are each pro-l vided with channelscorresponding with those of the main magazine A, a pair of transverseribs a a atthe bottom of the magazine, projecting beyond the lateraledges thereof, 'a shorter transverse rib a at the leading edge of themagazine and the usuallocking bar A for preventing supporting frame(Fig. 8), a, pair of supporting surfaces are presented upon which theauxiliary magazine rests with its channels, in alinement with thecorresponding, channels of the main magazine. Each of the levers isfurther, .pro:- vided with a retaining lug a -at its forwardend arrangedto engage the lower transverse, rib al, to maintain the auxiliarymagazine in, position on the supporting levers.

The machine is also provided withiaflhinged magazine entrance channel Jlbetween the distributor mechanism and the entrancerend'of' the magazine'A, which may be turned downwardly out of the way of the auxiliarymagazine A from which the matrices are to be transferred to' the mainmagazine; The auxiliary magazine A is held in position to transfermatriceslto the magazine A by a pair of lugs a l, one (arranged at eachof the upper corners of themagazin'e sup"- porting frame A and uponwhich the front edge of the auxiliary magazine rests with" thetransverse rib a banking against the rear fa'cesfof the lugs, and by apair of brackets'A supported by the distributor frame at the oppositeends thereof. The bracketsare each providedl attheir iii" rear ends witha spring actuated dog a arranged to engagebeneath-ithe upper. transverserib a of the auxiliaryv magazine, andat the ends there-- of to maintainthe magazine in aiposition,-where its channels aline with thecorresponding channelsof the main magazineis. Thus, in order to. placethe'auxiliary. magazine-1A in position it is necessary only to rest thefront edge thereof on the magazine supporting frame'A and push therearportion of thexmagazine'upwrtilengaged by the spring actuated dogs e.yInrorderi toitransfer the matrices from the main magazine Atotheauxiliary storage magazine, A the -matrix=-lock of the-latter is firstlooked andthe matrix lock of the main :magazine unlocked, whereupon the.matrices. willvslide :out ofthe channels of the ,main; magazine. intothe corresponding channels of the :iauxiliary magazine-.- The lockof themain magazine is then looked, and that of the uppergauxiliarymagazineA kunlocked, whereuponthematrices will,

slide fromathe channels ofthelatter into the corresponding channels ofthemain magazine.

The-storage vmagazines are then removed and the mainqmagazine lowered toits normal-positionby the rearward movement'of the levers A Theadvantageof the-auxiliary magazines re-, sides in thefact thattheymay befmadecheaply, thus obviating the-necessityfor a number of main magazinescorrespondingvto the different fonts desired tobe'usedwith the machine.They are particularly desirable in a machine such as that described inmy copendingapplication, Serial No. 677,417, wherein the main; magazineis much wider than usual being designed chiefly-for use withfheadletter? matrices -and consequently more expensive than standardmagazines, 1 i, V In ,view of the previous descri tionyit is be; lievedthe invention will be. readily. understood without entering. into afurther description of; theoperation of the machine ,In the accompanyingdrawings the invention hassheenoshown merely by way ofexample. and inpreferred form, and obviouslymany variations andfmodificationsfmay bemade therein which will stillbe comprised within its spirit. It is to beunderstood, therefore, that the invention is not limitedto, any specificform-or embodiment, except insofar as such in the [appended claims.Having thus ,described my invention, what I claim as. follows: I
